CARPENTER S WORK-SUPPORT.

Specicatioiiof Letters Patent.

Patented Oct. 16, 1917;

Application filed August 12, 1916. Serial No. 114,581.

T0 @ZZ whom t may concern: f

Be it known that I, Gaone F. Knnienn, a citizen of sthe United States,and resident of Grand Rapids, in the county of food and State oflVisconsin, have invented certain new vand useful ImprovementsinCarpenters7 Work-Supports, of which the following is a specification.

The present invention relates to new and useful improvementsincollapsible supports for carpentry work Vand forvthe use of mechanics,the same having particular reference to that class of devices known ascarpenters horses The primary object of my invention is to provide aycarpenter-s horse having means associated therewith for connecting thesupporting beam and legs. i

Another object of my invention is to provide improved means forconnecting the beam and supporting legs of a carpenters horse or thelike, whereby said legs and beam may be Lreadily disconnected to renewthe beam or one of the legs as the `case ymay be.

course, as will appear from the followingdetail description, I do notlimit myself to tlieuse of the device for connecting beams andsupporting legs, since by increasing the size of the yoke and connectingelements the same may be employed for various kinds of structural work.

A further object of my invention `is to provide a device'of the classdescribed which may be cheap to manufacture, strong and durable, andeffective in operation.

v@ther objects and advantages to be 'derived vfrom the use vof myimproved carpenters horse will ,appear from .the following detaildescription and the claims, taken with 4an inspection of theaccompanying drawing, in which:

Figure l is an end elevational view assembled, of a carpenters horseembodying the improvements yof my invention:

Fig. 2 is a side elevational view of the same;

Fig. 3 is an enlarged fragmentary sectional view of the connectingelements;

Fig. t is an enlargedfragmentary trans-v verse sectional view of themodified form'of connecting elements;

Fig. 5 is an enlarged detailed perspective of a Wedge member employed inconnection with the modified form of my invention as shown in Fig. 4;

Fig., 6 is an enlarged fragmentary side elevational view of a furthermodified form ofmy invention;

Fig. 7 is an enlarged end elevational view, partly in section, of astill further modified form of my invention; and

Fig. Sis a still further modified form of my invention.

Referring more particularly to the drawing, wherein similar charactersof reference designate like' and corresponding' parts throughout thevarious views, l designates the beam of the usual horse and 2 and 3designate the supporting legs thereof.

My invention resides speciiically in the yoke member or connecting thebeam and legs 2and 3, the preferred form of the same being shown inFigs. l to 3.

Referring to the form of my invention sho-wn in Figs. l to 3, I providea rectangular yoke member 4 formed of angledron adapted to embrace apair of legs 2 and `3 as the case may be. The upper free ends of thelegs 2 and 3are -beveled as at 5 to engage the opposite faces of thebeaml, said legs being relatively divergent. A screw spreading clamp 6 isinserted between the legs 2 and y3 adjacent the lo Ter ends thereof foran obvious purpose.-

For maintaining each of the yoke members d: in position on theirrespective legs I provide, with each yoke member a pair of strap members7, said strap members being -bent to conform to the shape of the upperend of the legs to which' the same are applied, the lower free endsofthe strap members being formed with stir-rups S for engagement beneaththe yoke member 4.

It will be seen thatwhen the yoke members and stirrup members are4applied to the beam and legs as vbest shown in Figs. l yto 3, and theclamp member 6 tightened, the legs will be caused to grip the beampreventing withdrawalof the same, the yoke memberbeing Vheld rigidly inengagement with ythe beam by virtue of the stirrup members 7 i vReferring to the modified form of my invention V'shown in F igspi and 5the beam hasbeen designated l and the legs 2. Of

course, only one pair of the legs has been shown in this case, but it isto be understood that the opposite end of the beam 9 is also providedwith the same structure as that shown. The yoke member is designated anddesignated 12, being engaged with-the voke member in a manner identicalwith the preferred form of my invention. However, in order to obviatethe necessity of beveling the leg l provide a pair of vwedge members 13,one of which is shown to advantage in Fig. 5. The wedge member isprovided with side {ianges le, adapted to forma longitudinal recess toreceive the upper end of the leg, the surface of the wedge beingcorrugated as at 15 to prevent slipping of the leg. The lower ends ofthe wedge member 13 are provided with lateral flanges 16 for engagementbeneath the beams. The Wedges engage above the yoke members, so that theyoke members assist in retaining the wedges in position.

In Fig. 6 I have illustrated a further modified form of my inventionwherein the beam is designated 1 and one of the legs 2. A clamping block19 is provided, said clamping block being U-shaped in crosssection andhaving a rib 2O on the outer surface thereof. The free ends of the riby2O are enlarged and provided with pairs of apertures 21, a certain pairof apertures being adapted to receive bolts 22 when the block is appliedto the legs, said bolts passing beneath the beam into a blocksimilar tothe block 19, arranged on the opposite side of the beam. The formationofthe enlargements and openings permits reversal and interchangeability`of the block 19.

Referring to'Fig. 7, I have illustrated a further modied form of myinvention in which the beam is designated 1 and the supporting legs 2,The upper free ends of the legs are beveled as at 25, or may be straightand the wedges 13 employed. A yoke member et is provided, said yokemember being practically identical in construction with the yoke members4l and 11 hereinbefore described. A plurality of bolts 27 extendtransversely of the beam beneath the same and lthrough said yoke membersretaining the yoke in the desired position, nuts 28 serving to retainsaid bolts in position. A. spreading brace 29 is inserted between thelegs 24 to maintain the same in clamped position. A Referring to themodied form of my invention shown in Fig. 8 l provide a rectangular yoke4a having inclined ends 33 and twisted sides forming saddles 34. A pairof Copies of this patent may be obtained for masses pins 3,5 are carriedby each ofthe saddle portions to receive a beam, the legs being receivedbetween the inclined ends and the beam. The pins prevent lateraldisplacement of the beam and the inclined ends cooperating with the pinsand beam serve to grip the` legs.

The use and advantages of my improved support will be readily apparentfrom the foregoing description and the drawing. It is apparent that inall of the'forms of my invention the parts thereof are interchangeable,that is, the yoke members in each form are practically identicaland ifdesired the wedge members may beemployed in connection with the formofthe invention shown in Figs. 1 to 3 orV in connection with the formshown in Fig. 7. desire to lay particular stress upon the novel mannerin which the members lmay `be quickly and easily disassembled when notin use.

From the above description taken in connection with the accompanyingdrawing, it is thought that a clear and comprehensive understanding ofthe construction, operation and advantages of my invention maybe had,andV while l have shown and device as embodying a specific structure, ldesire that it beunderstood that such changes may be made in saidstructure as do not depart from the spirit and scope of the invention asclaimed.

Having thus fully described my invention, what l claim as new and desireto secure by Letters Patent, is: ,Y

l. The combination with a beam, and supporting legs, of means forconnecting said beam and legs including a yoke member to encircle thelegs, stirrup members carried by the upper free ends of said legs to'engage said yoke member to maintain the same in engagement with saidlegand said beam.

2. ln a support, the combinationV of a beam, supporting legs therefor, ayoke member for engagement with said legs, said yoke member beingengageable beneath said beam, stirru'p members carried by the upper freeends ofthelegs for engagement with said yoke member to maintain the samein endescribed` the` gagement with said beam, and wedge'means Gaone F.immens.. y
